Aluminium alloys are alloys in which aluminium is the predominant metal. Aluminium alloys of 5xxx series and their welded joints show good resistance to corrosion in sea water. TIG welding technique is one of the precise and fastest processes used in aerospace industries, ship industries, automobile industries, nuclear industries and marine industries. In order to optimize any process it is very essential to understand the effect of its process parameters on mechanical properties of selected substrate. On the basis of the literature reviewed it has been observed that still there are limited research studies on optimizing the process parameters of Pulsed TIG welding of AA5083-H116.
